Carrier furnace mmodel # 58dla110---10122 with hk42fz014 control board will not start

There should be a wiring schematic on a panel inside the unit. Otherwise search for a service manual, using the furnace model number. With some luck, perhaps wire colors are shown. Otherwise, trace them to their origin and label your drawing.

Make sure the kill switch on the blower door is closed, or furnace won't do anything. Then remove power from furnace for a few seconds, then try again. Still no go? Take a jumper wire and jump the "r" terminal to the "w" terminal on the furnace's board. This bypasses the thermostat. This is only for testing. If it still wont run, call service guy. Gas furnaces are not good things to tinker with.

Unplug the ignitor and check it for continuity. If it checks good see if it is getting power from the board.

Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:

1. Thermostat calls for heat.

2. Draft inducer motor starts.

3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes.

4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution: You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. Please see "limits, rollout switches & furnace control boards" further down on this page. The furnace's control board might not be supplying the voltage to the ignitor. If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

Your Carrier guys more than likely are Carrier dealers. I would get a second opinion. Most qualified HVAC techs can work on any and all brands. It doesn't need to be a Carrier dealer to work on a Carrier. AND, if they replaced the control board and didn't test the heat, that's a fault on their part. Anytime we change a board or even a thermostat, we check ALL modes and functions. SECOND OPINION!!!

Normally the Ignitor is easily removed with 1 screw....be careful its very brittle and obviousy turn the power off first...you likely will see a very small crack in the ignitor and a "Hot spot"...it may also be defective even though it's not cracked...the best thing to do is unplug the ignitor and recycle the furnace checking for 120 volts at the Ignitor shortly after the fan starts and before it stops...If you have 120 volts and the ignitor isn't lighting up then it's defective....if you have no power to the ignitor it is something else and requires more info...look for an error code (Lights flashing on the circuit board)

Inspect flame sensor, (located in burner area, opposite side of hot surface ignitor). If the tip of sensor have a white carbon build up on it, it needs to be removed and cleaned, Good luck.

sounds like the sensing bar on the spark ignition is dirty.....a wire brush works nicely.
